From a97baa799a8069fe965a4d194935c025e21acf8e Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.org>

Subject: [PATCH] staging: bcm2835-codec: Refactor default resolution
code
The default resolution code was different for each role
as compressed formats need to pass bytesperline as 0 and
set up customised buffer sizes.
This is common setup, therefore amend get_sizeimage and
get_bytesperline to do the correct thing whether compressed
or uncompressed.
